Core Tip

Core tip: The number of laparoscopic sleeve gastrectomies (LSGs) performed worldwide as a primary bariatric procedure has grown exponentially in recent years, given the simplicity of the technique, the low complication rate and the good short- and mid-term results regarding weight loss and the resolution of co-morbidities. However, there are a limited data from long-term studies. In this study, a standardized LSG proved to be safe (no mortality and a leakage rate of 1.2%) and highly effective in terms of weight loss after 5-year of follow-up, particularly in patients with a low preoperative body mass index. This manuscript provides additional evidence supporting the role of laparoscopic sleeve gastrectomy as a stand-alone procedure for selected morbidly obese patients.
